Product description Cooling (option) The (usually) water-cooled gas cooler must be positioned at the gas outlet port of the pump. In addition, the pump temperature needs to be monitored by a thermostat, which switches off the pump, if the preset temperature limit is exceeded (e.g. due to failure of the cooling water system).
Installation Installation CAUTION Loss of stability! Risk of injury due to the pump's tipping towards motor as long as the pump is not fas- tened to the base. Secure pump with suitable lifting device on motor side. Wear safety shoes with steel toe cap according to directive EN 347. Setting up the pump When installing the pump, observe the following conditions: ...

Installation Adding sealant for When using a mechanical seal (optional), a cooling of the sealing surfaces is required. The sealant reservoir needs to be attached above the shaft feedthrough on the outside the mechanical seal of the pump, on the base frame or in a different suitable location depending on the actual (versions with MS conditions.
Installation Connecting the vacuum side WARNING Exposed, rotating rolling pistons! Fingers and hands can become crushed when the intake flange is open. Keep all body parts out of operating range of the rolling pistons. Use a wooden handle to rotate the rolling pistons during cleaning. ...
These can be adapted by the operator or ordered from Pfeiffer Vacuum. The dimensioning of the cold gas recirculation line (7.1) should also be matched to the gas cooler and the pump.

Installation Motor protection With PTC temperature sensors (3PTC) Pump motors equipped with PTC temperature sensors (3PTC) in the stator windings can be connected to a PTC resistor tripping device for protection against overload. Other ap- proved motor temperature monitoring can be used also by the operator. Tripping devices store the shutdown event and need to be manually switched back on again via the integrated RESET button or via the external RESET S3.
Installation Connecting accessories The following accessories are not included in the delivery, and can be ordered separate- Sealing gas connec- The evacuation of high-boiling media (e.g. solvents) can be damaging to the lubricant. Damage can be avoided by letting in sealing gas (process-specifically) into the shaft pas- tion sageways between the operating chamber and the gear chamber.
Operation Operation Before switching on Check lubricant levels at both sight glasses and at the oiler as well. Protect the pump sufficiently from taking in contaminants by means of suitable precau- tions (e.g. protective strainer); if necessary, check lubricant regularly or replace at shorter intervals.

Operation Switch off the pump. Venting should be performed via the suction side, do not ventilate vacuum chambers through the pump. Stop flushing gas feed. Stop cooling water supply. Switching back on After switching off the pump it can be switched back on again within 5 minutes. If you wait any longer then leave the pump to cool to ambient temperature before switching back on again.
Maintenance Maintenance Precautions WARNING Exposed, rotating rolling pistons! Fingers and hands can become crushed when the intake flange is open. Keep all body parts out of operating range of the rolling pistons. Use a wooden handle to rotate the rolling pistons during cleaning. WARNING Pump parts may be contaminated from pumped media! Danger of poisoning due to contact with harmful substances.
Checklist for inspec- Certain maintenance and overhaul work should only be performed by Pfeiffer Vacuum Service (PV). Pfeiffer Vacuum will be released from all warranty and liability claims if the tion, maintenance required, below listed, intervals are exceeded or maintenance or overhaul procedures and overhaul are not performed properly.
